box.contains()

My classmate showed me a photo that he took in a class. It had the whiteboard, which the teacher had written some code on it. My classmate wanted to me see what was wrong about it. I didn't get it. He then pointed to this line that had:

box.contains(click)

I saw it... The c and the l in 'click' were hand written too closely together. hahahahaha. box contains... hahahahaha. Then I said, "oh, that! I think Justin Timberlake had a video about it." He was surprised I got it, so exactly! hahaha

hahaha, pay attention to your handwriting and variable names. hehehe

Here's the link to the video (for mature audience. 小朋友不要學，叔叔有練過). I'm sure there are people who do that for the Valentine's gift somewhere in the world today.
